fsys Digi-Grove full stack Open-Source Model Server in
the Real-World Lab for Digital Sovereignty
Digital, Eco-Social and Sovereign
Digital independence and open solutions are essential,
especially in non-profit work and international
development cooperation. Our Mittwald vServer for our
intercontinental educational game initiative on
Regenerative, Sustainable and Climate-Resilient
Food Systems
has been serving for four years with a full range of
self-hosted Open‑Source solutions for various project
needs.
With project partners from city administrations,
ministries, youth organizations and international
research groups, we have been able to work
collaboratively on our server, publicly document in
real-time on our project websites, share results via an
open cloud as a common good, switch to our own AI models
and demonstrate the possibilities of digital
independence as a practical case study in the ESD
Real-World Lab.

With our managed vServer provider
Mittwald in Germany we have found, in
many respects, the ideal social tech and stack solution
provider. The team is exceptionally committed in the
increasingly complex topic of cloud infrastructure,
consistently delivers solutions that match our daily
practice as freelancers and agencies, and always
provides fast, approachable and personal support. The
carefully designed user experience in the server
administration, the performance and the very good global
accessibility are also fully met.
Since we work with project partners such as
Alliance of Biodiversity International
and
Consultative Group for International Agricultural
Research CGIAR
in the field of agroecology and climate protection
landscapes, the choice of server provider is also
important to us from this perspective. Here too,
Mittwald as a finalist in 2026 for the German
Sustainability Award is an ideally suited solution
provider for us.
Through the
Bloom Sponsorship at Feldwerk
Mittwald promotes biodiversity and creates living spaces
alongside server spaces. For the Mittwald reforestation
project, they planted a 27,158 m² agricultural area
with native tree species in November 2021. Since then
the „mittWald“ has been growing.
Additionally, they acquired a 31,210 m² forest area
at their location in Espelkamp to preserve the forest as
a natural CO2 sink – something that
connects us across borders with our project partners in
Kenya, who have firmly integrated reforestation programs
into school curricula and with whom we use our
applications on the Mittwald server.
Thus our server host supports our
fsysgame.org
Full Stack Open Source vServer not only with open social
technology, but also promotes, in accordance with our
values, national climate goals as well as the
preservation and protection of our regional ecosystems.
For the server costs, we currently rely on donations and
want to finance the fsys server initially until the end
of December 2026 with this campaign. The permanent,
long-term financing is currently being calculated into
an overall fsys financing plan.
